The Cretaceous Kurihashi Granodiorite in the Kitakami Mountains contains no monazite grain. To date the emplacement time of the Kurihashi Granodiorite by the CHIME method, monazite in a hornfels from the immediate contact of the granodiorite, instead, was analyzed. A total of 159 analyses on 17 monazite grains define an isochron of 117.7±2.0 Ma with an intercept value of 0.0005±0.0005. This age can be interpreted as the time of monazite formation during the contact metamorphism due to the emplacement of the Kurihashi Granodiorite.
